Small current, LED floodlight temperature rise is not obvious. If the ambient temperature is high, the main wavelength of the LED floodlight will be redshifted, the brightness will decline, and the luminous uniformity and consistency will become worse. In particular, the temperature rise of dot matrix and large display has a more significant impact on the reliability and stability of LED floodlights. So thermal design is key.

Floodlights shine uniformly from a specific point in all directions, and are best compared to light bulbs and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the range of the camera, or inside an object. It is common to use many different colors of floodlights over long distances in a scene. These floodlights can cast shadows and blend them onto the model. Due to the relatively large exposure range of the floodlight, the illumination effect of the floodlight is very predictable, and there are many auxiliary uses of this light, for example, the floodlight is placed near the surface of the object, which will produce bright light on the surface of the object
